S&C’s Manhole-Style Vista UDS features the standard Vista three-pole load-interrupter switch, completely sealed in a rugged stainless-steel tank and insulated with SF6 gas. The cylindrical tank measures 29.5-inches in diameter to fit through most manhole openings. Cable entrance and exit is via 600-amp bushings or optional 200-amp bushing wells. The unit is available through 15.5 kV at 630-amps continuous.

The quality of Vista’s gas-tight SF6-insulated construction is unprecedented. All gas seals have been extensively tested and field-proven, and every part of the unit is fully submersible in the most hostile environmentsl The extremely large viewing window and internal 3-position (closed-open-ground) switch provide a clearly visible open point.

With its compact design, rugged construction, and internal visible open point, the Manhole-Style Vista UDS is perfect for switching main feeders, radials, or networks in areas where installation space is restricted. Virtually any orientation or mounting style can be accommodated.
